NOTE: The factory default value for normalization temperature
is 25 °C. If you need to normalize to a value other
than 25 °C, see Section 6.6 – Normalization
Temperature.
4.3 Selection of Automatic or Manual Calibration
This meter is capable of performing either automatic (only CON 6) or manual
calibration.
In the automatic calibration mode, the meter (only CON 6) automatically detects
and verifies the appropriate known calibration standards solutions being
calibrated before accepting these particular calibration standards as one of its
calibration values in a specific measurement range. This automatic calibration
mode frees you from cumbersome calibration procedure.
The known calibration standards used for automatic calibration are:

CON 6 25 °C 1. 84 µS (for 0 – 200 µS/cm)
2. 1413 µS (for 0 – 2000 µS/cm)

Table 1: Conductivity Calibration Standards for Auto calibrations
In the manual calibration, non-standard calibration values can be used for
calibration. You can manually input the appropriate values as your desired
calibration standards in each specific range. This is useful when you have a
customized calibration standard specifically unique for your application.
To select Automatic or Manual Calibration settings, refer to Section 6.3 –
Automatic Calibration for more information.
